ROOFING ATTAcHMENT.

Application filed June 3,1920. Serial No. 386,260.

- This invention relates to flexible sheet material adapted to be applied to a'building structure for the purpose of weatherproo the same, and has forits object to provide, as a new article of manufacture, flexible sheet material of this kind which will be cheap to produce, can be applied with minimum labor and will be very efiicient in its anchorage to the building structure to which it is applied and in the weatherproofing of joints between the several sheets of the material.

The invention proceeds upon the principle of forming a piece of sheet metal, to provide an attaching base or plate through which it maybe mounted upon the flexible roofing material in advance of application of the sheet to the building structure and independently thereof, and a tang or spur thereon presented in position to be driven. into the surface of the structure'which is to receive the roofing material or through an overlapped roofing sheet, or presented partly in position to enetrate the building structure and partly in position to penetrate and interlock with an overlying roofing sheet; the attachments in some instances being made in form to coact one with another so that when applied, respectively, to overlapping portions of two sheets, they will serve as a.

means for uniting the sheets either incidentally to the penetration of the spurs into the building structure, or, in some instances, wholly separate from ing the roof to the building structure. In some embodiments of the invention the roofing material is provided with marginal laps or covering strips adapted to additionally,

seal the joint between the sheets, which is effected through the medium of the metal attachment and protect the anchoring means.

A number of embodiments of the several features of the invention are shown in the accompanying drawings by way of illus-' tration. In said drawings- Figure 1 is a perspective view showing. an embodiment of the invention in which the attaching base overlies the margin of the sheet and the anchoring spurs pro ect past the edge thereof.

Figure 2 is a view similar-to Figure 1- showing a modified form of anchoring spur which is designed formation under a ammer.

the feature of anchorarticularly to resist de- Figure 3 is a view showing the applicat11on of one form 'of the invention to shines.

' Figure 4 is an inverted view of a shingle entering into the combination of Figure 3 and showing .the attaching base cemented to the under side of the shingle.

Figure 5 is a detail view of an anchoring attachement with depending flange and with the spurs limited to the ends thereof.

Figure 6 is a perspective view showing a modification of the device shown in Figure 5.

Figure 7 is a further modification of the device shown in Figure 5 with specially formed end spurs. a

Figure 8 illustrates one use for which the forms of devices shown in Figures 5, 6,

and 7 is especially adapted in anchoring the roofing material.

Fi ure 9 is a view similar to Figure 1 showing the attaching base inset with respect to .the roofing sheet.

Figure 10 shows a modified construction ot the attachment of Figure 1 in which openings are formed to admit lap cement or bituminous matter to the surface of the roofing" sheet upon which the attaching base lies in order to insure adhesion.

Figure 11 is a View representing one method of securing the anchoring attachment to the under side of a sheet, namely, means of bituminous or other like cement.

Figure 12 represents a'modified constructionoianchoring attachment in which a weatherproofing apron is provided on the edge of the ing spurs.

In Fillllle ble roo g material, and 2 represents anchoring spurs with which said sheet is provided and through the medium of which the sheet may be anchored-to ture by embedding the spurs therein. To mount thespurs upon the sheet, they carried by an attaching base 3. In the present instance this attaching base overlies the margin of the sheet to be anchored and a building structhrough 1, 1 represents a sheet of flexicement. Bituminous cement is especially adhesion to metal.

As illustrated in I Figure 2, anchoring spurs 2*v may be formed upon the base 3 overlying adapted forthis purpose because of its firm the sheet 1 in a manner to present a percussion head 2? that will better adapt the spurs to withstand the blows of a hammer without bending. As further illustrated in Figure 2, the attaching base 3 maybe embedded in the sheet 1, as shown at 4.

According to Figure 4, the attaching base 3 is cemented to the under side of the roofing material and has its spurs 2 projecting from said under side. This is of particular advantage when the anchoring attachment is to be used for shingles 5, as illustrated in Figure 3.

As suggested in Figure 5, the base 3 may have a depressed flange 3 and may have its spurs 2 at the ends thereof, thereby leaving an extended unobstructed space between the spurs. These spurs may be attached to the longitudinal edge of the base, as suggested in Figure 8, or to the transverse or end edges as suggested in Figure 9. In all the forms, the spurs may be of plane triangular form, as suggested in most of the figures, or they may be shaped up to develop narrower form, as suggested in Figure 7, and this may be done by either cutting away the sides of the spurs, or by. folding, pressing, or otherwise shaping them.

The anchoringattachment of Figures 5, 6, and 7 lends itself with special advantage for securing the roofing material in the manner suggested in Figure-8, according to v which one margin 8 of the roofing sheet 1 is caught under the base 3 while the attachment is being driven into the roofing struc ture, and then the sheet is folded over the attachment with or without theuse of seaming cement between the attachment and the material of the roofing sheet.

Figure 9 suggests a relationship of the anchoring attachment substantially identical with Figure 1, except that the roofing sheet 1 has been prepared with'a recess or reduction of its thickness at 1 to admit the attachment and keep the outer surface of. the latter subst'antially'flush with the surface of the roofing sheet.

Assuggested in Figure 10, thebase 3 may be provided with openings '10 which will expose a portion of the surface'of the roofing sheet upon which the base is laid, thereby admitting to the surface of the roofing ma-. terial the seamingcement which binds it to an overlaid sheet, and securing better adhesion.

Figure 11 shows application of the anchoring attachment to the roofing material in a position back from the edge. It is secured in this position by the adhesive quality of the seaming cement which, when of proper consistency, strongly adheres to metal as well as the roofing material. The arrangement suggested in Figure '11 is es pecially advantageous for anchoring the overlapped marginof the sheet or shingle without disclosing the anchoring attachmentto view.

According to Figure 12, the anchoring attachment, and especially when applied to the sheet- 1 in the position of Figures 1 and 9, may have an apron'17 which drops from the upper surface of one sheet to the upper surface of an overlapped sheet and assists in weatherproofing the joint between them and such an apron 17 may have a bearing flange 17 through which it bears upon the overlapped sheet. This arrangement of apron isnot broadly claimed in this application, as it is described and claimed in my previously filed application, Serial No. 344,322, but is herein claimed in combination with anchoring or attaching spurs 2 projecting from the edge of the base 3 as shown in Figure 10.
